Description

TECHNICAL FIELD The present invention relates to an apparatus and method for measuring trajectory and dispersion of dispersed carbon particles using active RFID,

The present invention relates to a device for measuring trajectory and dispersion of dispersed carbon particles using active RFID (Radio Frequency Identification) and a method of measuring the same. More specifically, the present invention relates to a method for measuring the distribution of coarse particles of an induction and rocket weapon system using dispersed- And the trajectory of the dispersion charcoal using the active RFID, which provides the measurement technique using the active RFID (active RFID) to measure the trajectory of the jatrophy, A dispersion meter, and a measuring method thereof.

RFID (Radio Frequency Identification) is an Automatic Identification and Data Capture (AIDC) applied to ubiquitous computing technology of RFID / USN. It attaches an RFID tag to a product, a food or an object, The RFID reader recognizes the RF carrier signal for each frequency band using the RFID reader and recognizes the information about the product or object from the RFID tag as contactless and manages the tag information in the computer.

The RFID tag is composed of a small wireless IC chip, a memory, and an antenna. It is attached to ordinary products, foods, and objects, and stores information on production, delivery, distribution, Based on this, it manages distribution logistics information to remote server through mobile communication network, internet, and satellite communication network.

An RFID tag is divided into a passive tag that does not include a power source, and an active tag that includes a power source or a CPU. A passive RFID system transmits an RF carrier frequency signal to an RFID tag (transponder) on a forward link. The RFID tag receives the RF signal and performs amplitude modulation (AM) or phase modulation (PM) to return the data stored in the RFID tag to the RFID reader through the RF carrier frequency in a reverse link. The RFID reader decrypts the received modulated signal, decodes the RFID tag information, and manages the electronic tag information by connecting to a PC or a server on the Internet.

The RFID reader is divided into a fixed RFID reader and a portable RFID reader. Fixed type RFID readers are fixed to entry / exit, checkout counter, production line, and provide functions to read / write information of RFID tags. A portable RFID reader provides a gun type RFID reader or a handheld RFID reader.

The RFID reader transmits an RF signal to the RFID tag attached to the product, demodulates and decodes a signal received from the RFID tag in response to the RFID signal, reads the tag information, and transmits the TCP / IP, USB , CDMA, and the like, and manages information including the unique number of the product.

The RFID frequency used for the air interface between the RFID reader and the RFID tag is 125kHz, 135KHz, 13.56MHz, 433MHz, 860 ~ 960MHz, 2.45GHz, and the 860 ~ 960MHz band is mainly used for product distribution and logistics .

The 125kHz and 135KHz low frequency (LF) band RFID frequencies are the oldest technologies and have a recognition range of less than 60cm. They are slow in recognition rate and at the same time are not easy to read in large quantities. They are mainly used for access control, security and inventory management.

13.56 MHz High Frequency (HF) band RFID frequency is used in applications such as traffic cards, access control security, smart cards, etc., which are limited to data storage limit and metal environment but require short recognition distance.

The 433.92MHz UHF (Ultra High Frequency) RFID frequency operates only on active RFID tags, with a wide recognition range of 50m to 100m for military use and in the US for container management.

The 860-960 MHz UHF band RFID frequency provides wide recognition and read distances and fast data transfer rates and is used for distribution and logistics.

The 2.45GHz microwave band RFID frequency has characteristics similar to the 900MHz band RFID tag with a recognition distance of less than 1m and is used for product management and vehicle control with a small tag size. In the domestic market, RFID tags have the highest frequency band of 13.56MHz and 860 ~ 930MHz.

RFID      900MHz (UHF RFID)             13.56 MHz RFID reader - Long distance recognition (~ 1m)
- Short distance recognition
- Library, parking, inventory management RFID tag - B2C applications for distribution, logistics and B2B business purpose
-It is not suitable for ID identification due to security issue due to RF leakage - Widely used for transportation cards, financial cards, smart cards, ID cards
- mobile RFID information service using mobile phone

The working groups of ISO / IEC / JTC1 / SC31 have already established international standards using 125kHz, 135kHz, 13.56MHz, 433MHz, 900MHz and 2.45GHz RFID used frequencies, A standard for transmitting information read from an RFID reader to an application system was also established. In addition, EPCglobal uses the 900MHz frequency RFID technology to refer to the product's unique number, production information, and distribution history by attaching EPC code such as 96bit or 128bit to each product. In order to apply it to distribution and logistics field, ISO / IEC 18000-6 Type-C is the standard for wireless communication.

The Near Field Communication (NFC) Forum provides mobile RFID information services using mobile phones in the 13.56MHz RFID frequency band and EPCglobal's 900MHz RFID frequency band in the distribution and logistics fields (B2B and B2C).
